In a notable turn of events, the Federal Trade Commission announced that it would abandon its in-house post-consummation challenge of the 2018 acquisition by Axon Enterprise, Inc. of VieVu, LLC. The FTC’s decision follows a recent adverse ruling from the Supreme Court, which held that parties are entitled to assert constitutional challenges against the FTC before being required to participate in its administrative proceedings. Following the Supreme Court’s decision, the FTC is likely to confront more challenges when pursuing enforcement actions—including, in particular, merger challenges—through its in-house administrative proceedings.
